CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 434,025, dated August 12, 1890.

Serial No. 352,848. (No model.)

To all whom it may concern:

Be it known that 1, WILLIAM ROBERT PAR- at Raccoon, in the county of Marion and State of Illinois, have invented certain new and useful Improvements in Car-Couplings; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to certain new and useful improvements in car-couplings; and it has for its object to provide a simple, cheap, and efficient automatic car-coupling of few parts, and those not liable to get out of order or become inoperative.

The novelty resides in the peculiar combinations and the construction,arrangement, and adaptation of parts, all as more fully hereinafter described, shown in the drawings, and then particularly pointed out in the appended claim.

The invention is clearly illustrated in the accompanying drawings, which, with the letters of reference marked thereon,form a part of this specification, and in which- Figure 1 is a vertical section with parts in elevation, with the coupling-pin raised and the parts ready to couple with another car. Fig. 2 is a like View with the parts coupled. Fig. 3 is a bottom plan of the coupling-link.

Like letters of reference indicate like parts throughout the several views.

Referring now to the details of the drawings by letter, A designates a portion of a draw-head provided with usual opening a for the entrance of the link, and a vertical opening for the passage of the coupling-pin. lVithin a chamber 1) of the draw-head there. is pivoted on a transverse pin 0 a vertical plate B,provided at its upper end with a horizontal portion d,which is adapted to support the coupling-pin C, as shown in Fig. 1, when the car is uncoupled. On the end of the shaft or pin which carries this plate is a weight D,

.the tendency of which is to normally keep the pivoted plate in the position in which it is shown in Fig. l.

E is a stop-pin within the chamber of the draw-head to limit the forward movement of the swinging plate.

F is a support attached to the top of the draw-head and formed with an opening, through which the coupling-pin passes, the pin being provided with a collar or flange e to prevent its falling out.

G is the coupling-link, which is provided with spring-armsf, depending from its under side from near each end toward the center, there being an opening at each end, as shown at h, for the passage of the coupling-pin. These spring-arms are curved downward, as shown,and in use have a bearing on the wall of the opening in the mouth of the draw-head and serve to keep the link horizontal and allow of suflieient play thereof.

The operation will be readily understood. lVith the parts in the position in which they are shown in Fig.1 the device is ready to couple with another car. \Vhen the approaching car, which is supposed to carry the link, comes in contact with the link against the vertical swinging plate, the same is thrown back on its pivot into the position in which it is shown in Fig. 2, when the coupling-pin drops into the hole at the end of the link. When the pin and link are withdrawn, the

weight brings the parts into position to couple In testimony whereof I affix my signature in presence of two witnesses.

WILLIAM ROBERT PARKINSON.
